No cotton ball..

Make Your Own Cotton Ball

I didn't have any cotton balls to remove nail polish and I didn't want to use kleenex or toilet paper because it just shreds.

I had a little light bulb go off.. I grabbed some of my natural cotton yarn scraps (30-40inches) wrap it around two fingers a few times, then take off fingers wrap yarn around itself and pull tail through one side of the hoops (I used a small crochet hook to pull it through), give a little tug and you have something that works better then a cotton ball to remove polish!
